USER MANUAL
Designed according to the TS EN 60974-1
The EMU class of the machine according to TS EN 55011 is Group 2, class A.
Pls. see TS EN 60974-10 for detailed information.
• Do not switch on-off machine during welding. This may cause fluctuations in the mains voltage and shorten the service life of the machine.
• Wait for approximately 5-10 seconds after turning on the power unit to stabilize the machine, then start welding.
• This Class A equipment is not intended for use in residential locations where the electrical power is provided by the public low-voltage supply system. There can be potential difficulties in ensuring electromagnetic compatibility in those locations, due to conducted as well as radiated radio-frequency disturbances.
The welding machine is designed according to the relevant norms and rules. However, it may still cause problems for the telecommunication equipment (telephone, radio, television etc.) and safety devices susceptible to the electromagnetic fields as it generates electromagnetic waves. In order to reduce the effects of the electromagnetic waves (interference) generated by the machine, please read the following carefully.
The Welding machine is designed for operating in industrial areas. If it is used in residential areas, certain measures have to be taken in order to eliminate the possible effects of the electromagnetic waves.
Installation and use
General : The user is responsible for installing and using the arc welding equipment according to the manufacturer’s instructions. If electromagnetic disturbances are detected, then it shall be the responsibility of the user of the arc welding equipment to resolve the situation with the technical assistance of the manufacturer. In some cases this remedial action may be as simple as earthing the welding circuit (see note). In other cases, it could involve constructing an electromagnetic screen enclosing the welding power source and the work complete with associated input filters. In all cases electromagnetic disturbances shall be reduced to the point where they are no longer troublesome.
NOTE : The practice for earthing the welding circuit is dependent on local safety regulations.
Changing the earthing arrangements to improve EMC can affect the risk of injury or equipment damage. Further guidance is given in IEC 60974-9.
Assessment of area : Before installing arc welding equipment the user shall make an assessment of potential electromagnetic problems in the surrounding area. The following shall be taken into account:
a) other supply cables, control cables, signalling and telephone cables, above, below and adjacent to the arc welding equipment;
b) radio and television transmitters and receivers;
c) computer and other control equipment;
d) safety critical equipment, for example guarding of industrial equipment;
e) the health of the people around, for example the use of pacemakers and hearing aids;
f) equipment used for calibration or measurement;
g) the immunity of other equipment in the environment. The user shall ensure that other equipment being used in the environment is compatible. This may require additional protection measures;
USER MANUAL
77 h) the time of day that welding or other activities are to be carried out.
The size of the surrounding area to be considered will depend on the structure of the building and other activities that are taking place. The surrounding area may extend beyond the boundaries of the premises.
Assessment of welding installation
In addition to the assessment of the area, the assessment of arc welding installations may be used to evaluate and resolve cases of interference. An emission assessment should includ in situ measurements as specified in Clause 10 of CISPR 11:2009. In situ measurements may also be used to confirm the efficiency of mitigation measures.
Mitigation measures
Public supply system : Arc welding equipment should be connected to the public supply system according to the manufacturer’s recommendations. If interference occurs, it may be necessary to take additional precautions such as filtering of the public supply system. Consideration should be given to shielding the supply cable of permanently installed arc welding equipment, in metallic conduit or equivalent. Shielding should be electrically continuous throughout its length. The shielding should be connected to the welding power source so that good electrical contact is maintained between the conduit and the welding power source enclosure.
Maintenance of the arc welding equipment : The arc welding equipment should be routinely maintained according to the manufacturer’s recommendations. All access and service doors and covers should be closed and properly fastened when the arc welding equipment is in operation. The arc welding equipment should not be modified in any way, except for those changes and adjustments covered in the manufacturer’s instructions. In particular, the spark gaps of arc striking and stabilising devices should be adjusted and maintained according to the manufacturer’s recommendations.
Welding cables : The welding cables should be kept as short as possible and should be positioned close together, running at or close to the floor level.
Equipotential bonding : Bonding of all metallic objects in the surrounding area should be considered. However, metallic objects bonded to the work piece will increase the risk that the operator could receive an electric shock by touching these metallic objects and the electrode at the same time. The operator should be insulated from all such bonded metallic objects.
Earthing of the workpiece : Where the workpiece is not bonded to earth for electrical safety, nor connected to earth because of its size and position, for example, ship’s hull or building steelwork, a connection bonding the workpiece to earth may reduce emissions in some, but not all instances.
Care should be taken to prevent the earthing of the workpiece increasing the risk of injury to users or damage to other electrical equipment. Where necessary, the connection of the workpiece to earth should be made by a direct connection to the workpiece, but in some countries where direct connection is not permitted, the bonding should be achieved by suitable capacitance, selected according to national regulations.
Screening and shielding : Selective screening and shielding of other cables and equipment in the surrounding area may alleviate problems of interference. Screening of the entire welding area may be considered for special applications.
Not to be used in residential locations where the electrical power is provided by the public low-voltage supply system.
